IMPROVEMENT. IN CAMP-STOOLS.

Specification forming part of Letters Patent No. 163,623, dated May 25,1875; application filed December 26, 1874.

To all whom it may concern.-

Be it known that I, NELsoN R. ALLEN, of Norwich, in the State ofConnecticut, have invented a certain Improved PocketOhair, of which thefollowing is a specification:

The object of my invention is such a construction of a chair as willpossess the greatest stiffness and strength, when compared with the bulkand weight of material used, thus obtaining a chair in a very simple andcompact form, while, at the same time, its construction is such as toadmit of its being readily taken apart and rolled up into a smallpackage, so as to be carried either in the hand or pocket without anyinconvenience.

Figure 1 shows my pocket-chair put together ready for use. Fig. 2 is atop view, Fig. 3 is a bottom view, and Fig. 4c is a vertical section, ofthe center-piece, into which the whole frame-work of the chair isscrewed. Fig. 5 shows the bulk of the chair when taken apart and rolledup for carrying in the pocket.

A A are the seven pieces which form the whole frame-work of the chair.These pieces should be made of ordinary brass tubing, all being of equallength, and interchangeable, and about three-eighths of an inch indiameter, thus giving greater stiffness, with much less weight, thansolid rods, being of brass, because this metal is preferable to iron,and much tougher than steel, so that these tubes will spring and give,and not be liable to sudden breakage like steel. B is the centerpiece,which should be made onlylarge enough to admit of the insertion of theseven tubes, having a large vertical opening through it, thus making itmuch lighter, without detracting from its strength. The top and bottomof this center piece B are beveled off, as shown in Fig. 4, and have theseven holes drilled into it, as shown in Figs. 2 and 3, at right angleswith the top and bottom surfaces, and are tapped so that the ends of thescrewthreaded tubes A A may be easily and firmly screwed in. O is theseat, which may be made of carpet or other strong material, having twoof its sides sewed securely over the two rods 0 c, the ends of these tworods 0 a being bent downward at an acute angle, as shown, so as to admitof being readily inserted into the upper ends of the four upper tubes,thus completing the chair for use.

The under side of the seat 0 should have a pocket, as shown by dottedlines in Fig. 1, into which the whole seven tubes may be put afterunscrewing them from the center-piece, when the whole may be rolled up,as shown in Fig. 5, and inserted through the large hole in thecenter-piece, or tied up separately, as preferred.

It is believed that this chair possesses greater strength for use, andconvenience for carrying about, when compared with its weight and bulk,than any other hitherto devised.

I am aware of the patent of Geo. W. King, dated July 12, 1870, and,therefore, do not claim, broadly, the use of seat arms and legs hingedor pivoted upon the upper and lower ends of a cylinder; neither do Iclaim a tripod-stand, consisting of three legs screwed into the seat orbase, as shown in the patent of A. Iske, dated June 18, 1872 5 but Iclaim as my invention The combination, with the tripod base, formed bythe three tubular legs A screwed into the beveled annular central pieceB of the seat-frame, consisting of four similar tubular interchangeablearms, screwed into the same central piece B, having the parallel siderods 0 c inserted into their upper ends, and provided with the seat 0,for the purpose of making a cheap, light, and rigid pocket-chair, asherein described.
